GUARD-SCREEN FOR ROLLING-MlLLS.

SPECIFICATION forming part of Letters Patent No. 361193, dated July 26, 188'7.

Application tiled December 2, 1886. Serial No. 220,462. (No model.)

.To all whom, it may concern:

Beit known that I, FRED H. DANIELs, a citizen of the United States, residing at Worcester, in the county of Worcester and State of lvlassachusetts,h'ave invented certain new Vand useful Improvements in Guard-Screens for Rolling-Mills, of which the following, together with the accompanying drawings, is a specitication sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

In wire rod-rolling mills constructed for operating on the continuous system, and especially in those adapted for reducing the rods to asmall size, the latter rollsin the trainthose near to and including the final or :finish-y ing rolls-require to run at a high rate of speed,

andthe rod is projected forward with agreat velocity.

Owingto conditions of quality and defects or flaws in the metal worked, or by displacement or derangcment in the adjustment ofthe guides or rolls, it often occurs that the passage, ofthe :rod becomes obstructed and the rod overtlows or accidentally breaks out at some intermediate portion of the mill in a looseend or flying loop, and in case of such break-out 7 or accident, the probability of which proportionally increases with the increase of speed of the rolls, the escaping overflow or breakout of the rod is liable to be thrown inany unexpected direction and with the force of a projectile; hence the attendants deem it unsafe to stand near the latter part of a mill which is run beyond a moderate limit of speed.

The object of my present invention is to pro-` vide means for confining the overflow or broken-outend or flying loop ofrod and for protecting the attendants from liability toinjury, while affording facilities for observing the operation of the mill while the guard is in po.- sition, allowing quick and convenient access to the rolls and guides and ready removal for l permitting the clearing ofthe train from cobbles7 or tangled rodwhen required.

To this end my invention consists in a guard or screen constructed and adapted 'for use in combination 'with the rolling-mill, as hereinafter more fully explained, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure l-is a front view of y v thelattcr portion ofa continuous-rolling mill, showing my invention applied thereto. Fig. 2 is a transverse section at the position of linear and Fig. 3 is a horizontal section or plan view ofthe same.

Referring to parts, A denotes the rollingxnill, which may be a continuous mill of ordinary construction, and comprising, say, fourteen to twenty pairs of rolls, more or' less. At the latter end ofthe train II arrange a shield or plate of metal, B, preferably curved around the end of the mill, and also arched forward at the top. Said shield or plate is provided with a foot or flange, through which I arrange bolts b, forsecu ring it rigidly in po sition.

The spaces or openings for the bolts are slotted in from the rear edge of the flange, so that the shield can be released by moving it for- Ward, without the necessity of fully unscrewing the bolts. The deliveryguide G passes through an opening in the shield or plate B. Adjacent to the end guard or shield, B, and extending along parallel with the front of the machine, and at aV distance of about twenty inches (more or less) therefrom, I arrange an open-work screen or screens, C, the top of which is made rearwardly .overhanging or arched, in the manner substantially as indicated in Fig. 2, to cover and inclose the rolls 'and roll-housings of the mill, so that a brokenout end or flying loop of rod, if accidentally thrown out from the mill, will be interrupted and confined within the limit of the screen.

Along the front of the screen C, at positions corresponding with the guides or rolls,I arrange doors D, or movable portions of screen, which open and permit access through the screen to the roll-journals and bearings, and alsoto the intermediate guides between the sev- .eralV pairs of rolls. In the present instance the doors D are shown in a continuous series along the entire front of the screen; but a greater or less number might be used. Two sections of screen C are herein shown; but a screen or guard of one, two, three, or more sections, as desired, may be employed in connection with an end guard or shield, which latter is in the present instance made as a solid plate, or unperforated; but said shield might, if desired,

be perforated or made of strong wirenetting.

IOO

I prefer, however, to form it as shown. The

such height that a man can walk along the space between the mill and front of the screen beneath the arch or overhanging top when the mill is not running.

The doors or such portions of the screen as are desired to be opened or removed may, if preferred, be arranged to swing upward or outward from the mill, er may be arranged to slide longitudinally on suitable trucks or guides, or in other convenient man ner, so that space can be opened to allow ready access to such portions ofthe mill as may require attention.

The foot of the screen is preferably secured to the floor by detachable connections t', and the several sections of screen are connected by chains E, or equivalent means, with a counterbalancingweight or with a suitable hoistingdrum, F, whereby the screens can at any time desired be raised or hoisted up clear of the mill, thus leaving an open and unobstructed space for the convenience of clearing away eobbles or break-outs of rod, or for removing and replacing rolls, guides, or housings, or making any kind of repairs on the mill, and thereafter quickly replaced in position by lowering it again into place.

XVhat I claim as of my inventiomand desire to secure by Letters Patent, is-

1. In combination with a wire-roda'olling mill, a metal or wovenwire guard-screen adapted to inclose the high-speeded portion of the mill, for confining accidental outflow or broken-out rods and wholly or in part removable to permit ready access to the mill.

2. A perforated or netted screen having an overhanging top and a series of doors, D, substantially as and for the purpose set forth.

3. The combinatiomwith a continuous wirerod-rolling mill, of a screen formed of netting or perforated metal, with an upright portion extending along in front of the mill, and an overhanging top inelosing the rolls and rollliousings, substantially as and for the purpose set forth.

4. The combinatiomwith a continuous wirerod-rolling mill, of a transversely-disposed guard, as B, at the end of the mill, and a guard or series of guard-sections extending along the front of the mill and overhanging the rolls and roll-housings, substantiallyr as and for the purpose set forth.

5. The combination, with a continuous rolling-mill, of a screen overhauging the rolls and housings at the top of the mill and capable of being raised or swung up to permit access to the machinery, and a supporting device in connection therewith for sustaining the overhanging portion of the screen and for facilitating the raising thereof, for the purpose set forth.

6. The combinatiomwith a continuous wirerod-rolling mill, of a removable screen of netting or perforated metal, and suspending devices whereby said screen is supported from above, and an elevating device to facilitate raising said screen away from the mill and lowering it into place, substantially. as and for the purpose set forth.

7. The combinatiomwith a continuous wire rod-rolling mill, of a guard or screen arranged along the front of the .mill and provided with doors or movable portions at positions corresponding with the respective guides or rolljournals, for permitting ready access to the same, substantially as set forth.
